Climate change, Nature August 2018

End of Antartic Isolation?

Genomic and oceanographic data show that floating debris, including rafts of living marine organisms, can cross the Southern Ocean and wash up on Antarctic beaches. Fronds of southern bull kelp (Durvillaea Antarctica, a non-Antarctic species recently found in Antarctica) floating on the surface of the ocean at Marion Island are pictured on the cover.

How to pay the price for carbon

It is increasingly clear that achieving the Paris Agreement goal of limiting warming to well below 2 °C will require radical decarbonization, the prospects of which have become closely tied to carbon pricing.

Carbon prices across countries

With country-specific development objectives and constraints, multiple market failures and limited international transfers, carbon prices do not need to be uniform across countries, but must be part of broader policy packages.

The dangers of disaster-driven responses to climate change

Low-probability, high-consequence climate change events are likely to trigger management responses that are based on the demand for immediate action from those affected. However, these responses may be inefficient and even maladaptive in the long term.

Sea-level commitment as a gauge for climate policy

A well-defined relationship between global mean sea-level rise and cumulative carbon emissions can be used to inform policy about emission limits to prevent dangerous and essentially permanent anthropogenic interference with the climate system.

Changing storminess and global capture fisheries

Climate change-driven alterations in storminess pose a significant threat to global capture fisheries. Understanding how storms interact with fishery social-ecological systems can inform adaptive action and help to reduce the vulnerability of those dependent on fisheries for life and livelihood.

From political to climate crisis

Political crises may exacerbate environmental conflicts by shifting conservation priorities. Research now shows that increased carbon emissions from deforestation in Brazil may compromise its goals under the Paris Agreement.

The atmospheric response to sea-ice loss

The coincident reduction of Arctic sea ice with increasing mid-latitude wintertime extremes has motivated much research on Arctic–mid-latitude linkages. A new study reveals that projected Antarctic sea-ice loss could also impact the Southern Hemisphere mid-latitudes through perturbations to the strength and position of the westerly winds.

Waves of invasion

Will the Southern Ocean’s relentless waves undo Antarctica’s ecological isolation? The discovery of a wayward piece of kelp and a simple numerical experiment set new expectations for the potential invasion of Earth’s most isolated continent.

Prioritizing biodiversity and carbon

Protecting and restoring forests to mitigate climate change also promises to help protect tropical biodiversity and ecosystem services. Analysis now shows that optimizing for carbon can come at the expense of protecting biodiversity, but there are ways to effectively pair the two.

Making carbon pricing work for citizens

Ambitious carbon pricing reform is needed to meet climate targets. This Perspective argues that effective revenue recycling schemes should prioritize behavioural considerations that are aimed at achieving greater political acceptance.

Current understanding and challenges for oceans in a higher-CO2 world

Ocean acidification, a result of increased levels of CO2, impacts the marine environment and its biology. This Perspective presents the current understanding of the issue and highlights future directions for research.

Ocean warming alleviates iron limitation of marine nitrogen fixation

The growth of nitrogen-fixing marine cyanobacteria Trichodesmium is limited by iron availability under current conditions. However warmer temperatures reduce the iron requirement, allowing greater growth rates and increased nitrogen fixation.

Threat of climate change on a songbird population through its impacts on breeding

Individual and metapopulation models together project that —under an unabated climate change scenario— warming could reduce breeding productivity of a currently abundant songbird enough to pose a risk of quasi-extinction this century.

Higher temperatures increase suicide rates in the United States and Mexico

A 1 °C increase in monthly average temperature is associated with higher suicide rates in the United States and Mexico. Combined with comparable analysis of depressive language in US Twitter updates, these results suggest a link between higher temperatures and mental well-being.

Near-future CO2 levels impair the olfactory system of a marine fish

Marine fishes exposed to elevated CO2 levels can have altered responses to sensory cues. Research now reveals a physiological and molecular mechanism in the olfactory system that helps to explain this altered behaviour under elevated CO2.
